I've primarily switched over to using 15/18mm scale miniatures for my fantasy games. These are the test paints for the Orcs and Goblins I ordered from Magister Militium
Don't worry though, TNBSCGS! is being designed scale agnostic! Many of the crucial distances of movement are dependent on the size of base a model is on, so there is no need to change numbers when playing in 28mm vs 15mm scales.
